Think back for a moment to a high school science or biology class. Can you recall learning about the differences between voluntary and involuntary muscles? A voluntary muscle is one you choose to exercise, like an arm or a leg. An involuntary muscle is one that moves without your consent, like an eyelid or a heart.
As you’ve grown in Christ you have probably discovered some behavioral tendencies that tend to flare up repeatedly. You always respond angrily to certain events. You talk harshly about certain people. Like the apostle Paul you want to do the right thing but you seem to invariably do the wrong thing. What should be voluntary, controlled responses turn into involuntary unmanageable reactions.
Make the choice today to defeat the power of sin through the power of the Spirit. Ask Him to govern your words, thoughts, and deeds. In time, you will notice that the Holy Spirit will supplant your established negative habits of the flesh with fresh, triumphant habits of the spirit. It’s your choice and His pleasure!
